ENG and neoplasm: In our analysis, we found higher values of MVD (CD105-MVD, 221.0/mm2 on average) in RC tissues in comparison with the results in the study of Svagzdys et al. (CD34-MVD, 193.0/mm2 on average), possibly due to the larger surface of the analyzed tumor tissue (0.612 versus 0.576/mm2) and the use of different endothelial cell markers [26].
